This is one product your doctor will never tell you about. It is very good for mild insomnia, nervousness or anxiety. L-Theanine is an amino acid and should be taken on an empty stomach. It is a GABA precursor. GABA is a calming neurotransmitter. You can try to take GABA directly but it does not work on most people because it does not cross the blood brain barrier very well. L- theanine does. This is a trial size and worth getting to see if it works for you.
The recommended dose by most sources is 100-200mg. This is 150mg and right in the middle.
You may find you need a little more or less. You may find you need a 100mg size capsule to accommodate such dosing.
It is a very good natural alternative to sleep and anxiety medications.

I love this stuff! Due to illness I wake up every few hours and cannot get back to sleep. I can take one of these every time I wake and get a few more hours sleep. I also like it to help calm me down. It is an amino acid so there is no chance of addiction and I spoke to the company and was told there is a cumulative effect when you take it every day. This is not a drug so you won't be hit in the face with the effects but I won't be without this stuff.

Theanine is important to me because I have a high stress job and getting older does'nt help. I'm a bus driver so the calming effect helps alot and it does'nt induce sleepiness which is good if you're driving.
